A while back I had sold the amp these tubes were purchased for. They all have 90% life remaining on them or better except for the Amperex BB about 75 % and Brimar which may have about 50% left. I purchased all NOS and I will provide any info that I can.
Telefunken (The Fisher label) purchased NOS I used for about 50 hrs personally
Asking $90 for pair
Brimar BVA ( label fading on one tube / have worn original boxes)
Psvane Treasure Brand new used 10 hrs max
GE 5751 green label mostly legible.
Sorry for the poor picture quality, my camera is going
